IMPROVEMENT lN CHAIN-BELTS.

Specification forming part of Letters Patent No'. 18 1,028, dated August15, 1876; a plication filed December 27, 1675.

To all whom it may concern:

Be it known that I, JACOB BEHEL, of the city of Rockford, State ofIllinois, have invented certain Improvements in Chain-Belts, of .whichthe following is a specification:

My invention relates to that class of chainbelts known as rag chains,which are used in harvesting and other machines in combinanation withwhat are known as sprocketwheels, for the purpose of transmitting powerfrom the prime mover, and consists of links of such construction as toadmit of being readily put together to form belts of any requiredlength. In case of breakage, a new link may be readily inserted, and,when in place, are not liable to casual detachment.

which will be hereinafter referred to, similar letters representssimilar parts.

The links B are, preferably, of rectangular form, composed of side barsA, which, in this instance are of rounded form, and are connected at oneend by a round crossbar, D, grooved, as at a. The other ends of sidebars A are connected by a cross-bar, O, the outer end of which is ofproper width to enter between the sides bars of the links, and is ofcircular-hook form, consisting of a portion of a circle greater than asemicircle, either edge of the circular hook. forming a lip, 11, toenter the groove a in end bars D when placed at the proper angle, as inFig. 4, which if then straightened, the end bars D will roll into thebooks 0, and the chain will be complete as in Figs. 1, 2, 3, 7, and 8.and cannot unhook unless brought to the same angle as in hooking. Forthe purpose of compensating for the weakening of the end bars D, inconsequence of the grooves a, they may be made of larger diameter thanthe side bars, as represented at D, Fig. 6, which will also increasetheir wearing-surface and render the belt more durable; or the side barsA may be made as deep as the diameter of the grooved end bar,

as seen in in dotted lines, Fig. 6, and reduced in width, making theirtransverse section of oblong formdeeper than wide. This constructionenables me to increase the width of of the book 0, and furnishes agreater hearing in the links in the same sized belts; and the sprocketson the pulleys can also be enlarged, which will increase the durabilityof both belt and pulley. I do not wish to confine myself to theparticular form of groove represented in the preceding figures, so longas they are substantially the same, and are used for the purpose ofconnecting and disconnecting the links, substantially in the samemanner, as it is evident that other forms of the groove may be employed,such as the circular groove as at a, Fig. 5.

Fig. 7 represents a belt, which may be constructed of any reasonablewidth, and consists of detachable links composed of side bars A, withround end bars D, grooved as at a, and hook end bars 0, provided withlips b, and are connected with one or more central bars, A. These linksare connected and disconnected in substantially the same manner as thesingle chain-belt above describedthe lips b on hook-end bars 0 enteringthe grooves 01, in round-end bars D, when placed together at the properangle, and, in being straightened, the end bars D will roll into theirhooked bearings, and the book ends of bars D will enter between thelengthwise bars A A, 850., of the links. When it is desired to employthe chain-belt for elevators, the links may be provided with holes, asat c, for the reception of rivets, screws, or screw-bolts, for thepurpose of securing the elevator-buckets to the belt. Or, instead of theholes, studs f, as seen in Fig. 8, may be cast on the links.

Fig. 8 represents an edge view of Fig. 7, in which E represents anelevatorbucket in place on the belt. When these belts are designed forlight work, and when a belt of single links of greater width isdesirable, as in small elevators, or when constructed of great widthwith intermediate lengthwise,

bars A, with a large amount of hook bearingsurface in the links, in suchand similar cases the links may be constructed with their lengthwisebars A and intermediate bars A of less depth and greater width than thediameter of ends of the links are cast on cores, sanded chills, or onchills, to make the hooks of proper form and size to receive theround-end bars D, without bending or fitting the hooks to the properform after they are cast.

Some of the advantages attending my improvement in chain-belts are asfollows: The

links as they come from the malleable works or foundry are ready to beput together to form the belt, and do not require bending or fitting oraltering; and the manner of putting them together is such as to offergreat leverage in forcing the links into position without the aid oftools, and furnish the same leverage in disengaging the links forshortening the belt or in substituting a new link; and the squareeudedlinks furnish the greater amount of bearing-surface on the sprockets ofthe driving and driven pulley, increasing the durability of both beltand pulleys. They allow belts to be readily put together, lengthened,shortened, or repaired, and furnish the greatest possible hearings oneach other. They prevent lateral motion of the belt, and may beconstructed of any reasonable width. The fierlitral lengthwise barsgreatly strengthen the .e t.

I am aware that chain-belts have been constructed of rectangular linksof various formssome with round-end bars, connected by an intermediatelink of hook form at both ends, which required bending over the roundbars of the rectangular links after they were placed in the hooks.Others have been made of links, with one end bar round and one of hookform, to receive the round-end bar of another link, after which the hookend required bendin g over the round bar. These I do not claim; but

I claim as my invention- 1. A chain-belt link, having one of its endbars grooved, as at a, and the other constructed with a coupling-hook,0, having lip b, substantially as and for the purpose described.

2. A chain-belt link, grooved, as at a, constructed with coupling-hooks0, having lips b, and one or more intermediate bars, A, connecting theend bars, substantially as and for the purpose described.

3. A chain-belt link, constructed with one or more intermediate bars, A,connecting the end bars D and 0, provided with grooves and lips, thehook portion of bar 0 entering between the intermediate and outside barsA and A, substantially asand" for the purposes described.

4. A removable link of rectangular form for chain-belts, havingthelongitudinal bars A A, flattened on their faces and provided with holesa or studs f, substantially as and for the purposes described;
